Question

A projectile is fired with an initial speed of 37.4 m/s at an angle of 45.0 ° above the horizontal on a long flat firing range.

Part A

Determine the maximum height reached by the projectile. 

Express your answer using three significant figures and include the appropriate units. 

Part B 

Determine the total time in the air 

Part C 

Determine the total horizontal distance covered (that is, the range). 

Answer 1

Given launch velocity,

Part A) Max height

Use formula

ANSWER:

Part B) Time of flight

Use formula

ANSWER :

====================

Part C) Range

Use formula

ANSWER:

===========================

Part D)

Given launch velocity,

Vertical launch velocity,

Vertical velocity after 1.30s

Use formula

Horizontal launch velocity,

Horizontal velocity after 1.30s

There is no acceleration in horizontal direction ,so horizontal velocity remains same

Velocity after 1.30s

Part D) ANSWER:
